JOHN A. BRILL, OF PHILADELPHIA, PENNSYLVANIA.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 642,956, dated February 6, 1900.

Application filed May 15, 1899.

T0 aZZ whom it may concern:

Be it known that I, JOHN A. BRILL, acitizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Oar-Trucks, of which the following is a specification.

My invention has relation to improvements in the bolster construction of a pivotal cartruck and to means for supporting acar-body thereon and, more specifically, to improvements on the truck shown and described in the application for Letters Patent made by G. M. Brill, Serial No. 697,880, filed May 6, 1898, although my hereinafter-described improvements can be utilized on trucks constructed otherwise than as shown in said application.

My invention therefore resides in the construction and combination of parts hereinafter described, and further pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a side elevation of a cartruck embodying, in part, my improvements. Fig. 2 is a sectional elevation transversely of the truck and a portion of a superposed carbody, the truck-section being substantially on the lines 2 2, Figs. 2 and 3. Fig. 3 is a plan view of a little more than one-half of the truck, and'Fig. 4 is aside elevation of a modified form of bolster.

Similar numerals of reference indicate corresponding parts throughout the several views.

The car-truck to which I have applied my invention consists, substantially, as follows:

At 1 are the wheels, 2 the axles, and 3 the axle-boxes.

The truckframe comprises the yoke or pedestals 4 and the top bar 5, connecting the pedestals at the top, and the lower pedestal tie-bar 6,.connecting the lower arms of the pedestals,the cross-bars 7, extending between the inner and outer members of the yokes below the axle-boxes, and extensions 8 from. the outer arms of the yokes or pedestals, which extensions are connected transversely at the end by cross-bars 9 to form a complete axle-box frame.

Between the top of the axle-boxes and the Serial No. 716,884. (No model.)

upper cross-bar 10 of the yokes or pedestals are springs 11, and supported from the top bar 5 of the side frames on each side and closely adjacent the yokes or pedestals are longitudinally-disposed semi-elliptic springs 12, placed directly under the top bar 5 and arched upwardly, the semi-elliptic springs being supported from said top bar by the ex tensible links 13, comprising the yoke or strap 14, engaging directly with the ends of the semi-elliptic springs, as shown'in Fig. 1, the upper pendent link or bolt being provided with an enlarged head 16, journaled in a corresponding aperture 17 in the top bar 5 and carrying a spring-seat 18 at the end, between which and the top cross-bar 19 of the strap 14 is inserted a spring 20,the parts being adapted to swing transversely and to allow of an extension of the links against the stress of the link-springs.

The construction of the truck and the means for supporting the bolster therefrom form no part of my present invention, and I do not intend that my said invention shall be limited to any particular or specific construction of such parts, excepting that a certain portion of my invention, hereinafter to be described, resides in the combination, with the side springs or semi-elliptic springs, (or a rigid equalizing-ham) of a bolster, side bearings on the bolster located either directly over or outside of the said springs or between the car side sills and the bolster end, the bolster carrying a center or pivot plate, and a car-body mounted thereon either with or without the entire weight of the car being taken on the side bearmgs.

The bolster, Fig. 2, consists, specifically, of a flat bar 21, arched up centrally, as at 22, to pass readily up between the car-sills, the central flat portion 23 of which supports the truck center bearing 24, of any suitable construction, on a higher plane than the bottom of the side sills 25 and the flat end sections 26. The ends 26 of the bolster are connected to the inner and outer upright bracket-shaped castings 26 27, having laterally-extending webs or shelves 28 29, disposed transversely of the truck, angular and outwardly-extending strengthening-ribs 3O 31, and side lips 33, the horizontal ends 26 of the bolster being placed 1 within these lips and resting on the shelves 28 29 of the brackets, to which the bolts 34, securing the bolster to these brackets, are secured. The brackets have pendent projections 35, having inwardly-extending intermediate lips 36, which receive the strap 37 of the spring 12, and bolts 38 pass between the pendent projections 35 for securing the springstrap and the spring between the brackets, which thus form an upwardly-extending yoke supporting the bolster on the side springs 12. The brackets 5, between which the brackets 2G rest, are claimed in a later application, filed December 18, 1899, serially numbered 740,637, and are therefore not claimed in this application. 2

Instead of using the side springs 12 as equalizersasolid barcan be substituted, and either form of equalizer may be hung from the truckframe, as desired.

As will be noticed, the shelf 28 of the outer bracket extends some distance beyond the side springs and considerably beyond the wheel-gage of the truck and the bolster ends extend to the outer limits of the shelf.

It must be understood that the extension of the bolster to the limits of the shelf 28 in some respects is not essential, as the side bearings could be placed on the shelf and the brackets tied together by other means.

At 39 are the side bearings of any desired construction, preferably as shown in the drawings, which in this case consists of a casting or plate of metal having pendent lips 40, embracing the ends of the bolster, and at 41 are the car rub-plates, secured to the side sills directly over the side bearings.

At 42 is the body-bolster, of any desired construction.

However, in order to give perfect freedom for radiation of the truck and movement of the bolster between and beneath the side sills of the car and to produce a low-placed carbody I prefer that the bolster be so constructed as to present a plane surface below the car-flooring and within the sills.

Abody-bolster construction which has been used with satisfactory results in the above regard is constructed as follows: At 42 is a flat bar secured to the bottom of the car-flooring 43 (or when the weight is taken on the center bearing to a cross sill or sills) and having right-angled ends 44 passing down and secured to the side of the side sills. At 45 is the body center bearing, which in the present case acts merely as a drawing and pivoting device, but which does not sustain the weight of the car.

In Fig. 4 is illustrated a modification in which the outer bracket 27 is reduced in height below the top of the inner bracket 26, the formers shelf 28 being on a much lower plane than shelf 29, the shelf 28 being curved upwardly and rearwardly, as at 28, the bolster ends 26 taking a further drop from the plane of the shelf 29 to the horizontal plane of the shelf 28 through the downwardly-deflected portion 26, the extreme and horizontal ends 26 resting on the horizontal portion of the shelf 28, on which latter rests the side bearing 39, combined with the rub-plate 41 and side sill 25, as previously described. This construction allows the car-body to be brought much lower down on the truck.

It will be noted by reference to Fig. 2 that the side bearings are outside of the side springs 12 and considerably beyond the truckwheel gage. This portion of my invention I consider of great importance, as this location of parts produces a very easy riding car and the downward pressure of the car weight brought upon the side springs is more direct than it would be were the side bearings located inside of the wheel-gage or the plane of the side springs. I prefer that in this particular construction the weight of the carbody be taken, primarily, on the side bearings and the center bearings be used merely as means for drawing the truck or car, as the case may be, and to define the point of oscillation of the car and truck relative to each other. When so employed, the weight of the car falls, primarily, on the bolster through the side bearings either directly over or outside of the side springs, as may be desired, thus producing not only a direct action of the weight on the springs, but a considerable reduction in the transverse swing of the bolster and the springs, (which can be had through the swing-links previously described,) resulting in a support for the car in which the vertical movement of the body on the supportingspriu gs is made easy and the transverse swin g or oscillation of the car-body on the truck materially reduced.

The arching up of the truck-bolster centrally allows of the location and employment of two motors on the truck without mechanical difficulty, and consequently a short-wheel' base truck is produced, much shorter, in fact, than would be the case if the bolster had parts projecting down into the space between the truck side frames, which would prevent the motor extending under the bolster.

The taking of the weight of the car on the side bearings between the side sills and over or outside of the equalizers saves weight and bulk of body and truck bolster, the former merely needing strength for pulling, thereby doing away with heavy cross sills and braces extending into the car-body, either or both of which are used when the weight is taken on the center bearing.

The employment of the semi-elliptic springs is not essential to my invention for the purpose of equalization of the load, as an inflexible bar or equalizer can be employed, extending between the swing-links, in its stead, as before stated.

Having described my invention, I claim- 1. In a car-truck, the combination with the truck-frame, of longitudinallyd isposed equalizers, a bolster supported by the equalizers above and extending across and beyond the top bar of the truck-frame, side bearings at the outer ends of the bolster, and a center bearing on the bolster, substantially as described.

2. The combination with a truck having a truck-frame,of longitudinally-disposed equalizers, a bolster supported by the equalizers above and extending across and beyond the top bar of the truck-frame, a oar-body having side sills and a body-bolster, a center bearing extending between the truck and body bolsters, and side bearings extending between the side sills and truck-bolster ends, substantially as described.

3. The combination of a car-truck having a frame, a bolster extending across and above said frame, means for movably supporting said bolster on said frame, a center bearing on said bolster, and side bearings secured to said bolster above the truck-frame and exterior thereto, substantially as described.

4. The combination of a car-truck having a frame, a bolster supported on said frame and lying above the same, a car-body having a bolster, a center bearing having complemental parts on the body and truck bolsters, side bearings secured to the truck outside of the truck-frame, and complemental side bearings on the body-bolster, substantially as described.
